Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology in building engineering, and specifically to an auxiliary measuring device for concrete pouring. Background Technology

[0002] In concrete pouring construction, elevation and surface flatness control are of great importance in many aspects. For example, accurate elevation and surface flatness control is the foundation for ensuring that the dimensions of various building components meet the design requirements. That is, the elevation and surface flatness of the poured concrete must be measured and controlled during concrete pouring. By precisely controlling the concrete pouring elevation, it can be ensured that each part of the building structure is accurately positioned according to the design requirements, avoiding height errors, thereby ensuring the durability and aesthetic quality of the overall structure. At present, the technology usually involves marking the reinforced walls and columns. The concrete pouring elevation can be controlled at locations with reinforced walls and columns, while at locations without reinforced walls and columns, a level or laser instrument is required for control. During the concrete pouring process, because the concrete needs to be vibrated, the setup of these two instruments is inconvenient and inefficient. Furthermore, the elevation measurement cannot simultaneously take into account the measurement of the concrete surface flatness, requiring additional instruments for measurement, which is cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary measuring device for concrete pouring. This device, through a laser and junction box, can measure the concrete pouring elevation and surface flatness at the same time. It is simple and convenient to operate, and solves the problem of needing to set up multiple instruments for measurement in the prior art. The measurement is not affected by vibration operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary measuring device for concrete pouring includes a scale rod, a fixing frame, a laser, a reference elevation ruler, and a spirit level; the fixing frame is adjustablely mounted on the scale rod; the laser is mounted on the fixing frame and emits laser rays to the reference elevation ruler; the spirit level is set on the scale rod.

[0006] Preferably, the bottom of the scale rod is conical.

[0007] Preferably, a handle is integrally provided on the top of the scale bar, and the spirit level is provided on the top of the handle.

[0008] Preferably, the fixing bracket is slidably mounted on the scale rod, and a positioning screw is provided on the fixing bracket to fix the fixing bracket to the scale rod.

[0009] Preferably, a wire box is provided on the fixed frame. The wire box includes a housing, a grooved wheel, a crank handle, and a wire rope. The grooved wheel is rotatably mounted on the housing, and the wire rope is wound around the grooved wheel. The crank handle is mounted on one side of the grooved wheel, and rotating the crank handle can drive the grooved wheel to rotate.

[0010] Preferably, a hanging ring is also provided on the fixing frame.

[0011] Preferably, a protective sleeve is provided on the outside of the scale rod.

[0012] In this invention, by adjusting the position of the fixing frame on the scale rod cover according to the set reference elevation ruler, the operator can adjust the laser to the specified elevation position according to the elevation requirements, enabling accurate elevation measurement. The set spirit level facilitates the operator's adjustment of the vertical state of the scale rod. After connecting one end of the rope in the junction box to another scale rod, the surface flatness of the area covered by the rope along its length can be visually observed or measured with a ruler, simplifying the cumbersome operation of surface flatness measurement in the prior art. The set protective sleeve can prevent corrosion caused by direct contact between the scale rod and concrete. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1-3The illustrated auxiliary measuring device for concrete pouring includes a scale rod 1, a fixing frame 2, a laser 3, a reference elevation ruler 4, and a spirit level 5. The bottom of the scale rod 1 is conical, allowing it to be inserted into the bottom of the poured concrete, ensuring measurement accuracy and facilitating adjustment of its vertical orientation. The spirit level 5 is mounted on the scale rod 1, allowing the operator to adjust its vertical orientation and avoid measurement errors caused by tilting. A handle 6 is integrally mounted on the top of the scale rod 1 or attached via fasteners, with the spirit level 5 positioned on top of the handle 6. The operator holds the handle for easy measurement.

[0019] A graduation line is provided on the graduation rod 1, which can measure the concrete pouring depth at that location. By placing the graduation rod 1 in different positions, the operator can understand the concrete pouring depth at different locations. A protective sleeve 9 is provided on the outside of the graduation rod 1. The protective sleeve 9 is made of transparent rubber material. The protective sleeve 9 can prevent concrete from directly contacting the graduation rod 1, solving the problem of concrete fixing to the graduation rod 1 due to failure to clean in time. The transparent protective sleeve 9 does not affect the reading of the graduation line. After the operation is completed, the protective sleeve 9 can be directly removed for easy replacement.

[0020] The fixing bracket 2 is adjustablely mounted on the scale rod 1. In this embodiment, the fixing bracket 2 is slidably mounted on the scale rod 1. A positioning screw 7 is provided on the fixing bracket 2, which fixes the fixing bracket 2 at a designated position on the scale rod 1. A rotatable pad is provided at the end of the positioning screw 7 to prevent damage to the protective sleeve 9 when tightening the positioning screw 7.

[0021] The reference elevation ruler 4 is installed at a designated location on the ground via a bracket to provide an elevation reference. Figure 1 The bracket is not shown. The laser 3 is mounted on the fixed frame 2. After the laser 3 is turned on, it emits a laser beam to the reference elevation ruler 4, which can measure the elevation of the concrete poured at that location.

[0022] A wire box 8 is installed on the fixed frame 2. The wire box 8 includes a housing 80, a grooved wheel 81, a crank handle 82, and a wire rope 83. The grooved wheel 81 is rotatably mounted inside the housing 80 via a pin, and the wire rope 83 is wound around the grooved wheel 81. The crank handle 82 is fixedly mounted on one side of the grooved wheel 81. Rotating the crank handle 82 drives the grooved wheel 81 to rotate, thereby controlling the tension of the wire rope 83. To facilitate the control of the rotation of the grooved wheel 81, a limit hole is provided on the housing 80, and a limit pin is slidably installed on the crank handle 82. When the limit pin is inserted into the limit hole, the grooved wheel 81 cannot rotate, facilitating the control of the tension of the wire rope 83. Multiple markers 85 are provided on the wire rope 83, with adjacent markers 85 spaced 1m, 1.5m, or 2m apart. When measuring surface balance, the markers 85 are used as reference points for measurement.

[0023] A hanging ring 84 is also provided on the fixing frame 2. The hanging ring 84 facilitates the fixing of the wire 83. A wire outlet hole is provided on the housing 80. One end of the wire 83 passes through the wire outlet hole. The center position of the wire outlet hole, the center position of the hanging ring 84 and the center of the laser 3 are at the same horizontal height. When the wire 83 is taut, the elevation of the two ends of the wire 83 does not need to be adjusted again.

[0024] When it is necessary to measure the surface flatness of an area, multiple scale rods 1 can be used at the same time. The scale rods 1 can be fixed manually or by using auxiliary supports. Then, the ropes 83 are tied into a grid pattern or set in parallel to measure the surface flatness of the area to be measured.

[0025] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
